Hi ,
I am working in c# with crystal report XI.
I read an example about dynamic image location ..
1) In that we have a xml xchema file with two fields n amed country--datatype is string, img--datatype is base64Binary. using this as the datasource,i have designed the crytal report. And a parameter is set asking for the name.
2) I have designed teh form by adding a crystal report viewer and
now the coding part is as follows
// Prcocedure: AddImageRow
// reads an image file and adds this image to a dataset table
//
// [in] tbl DataTable
// country name of a country
// filename name of an image file
//
void AddImageRow(DataTable tbl, string name, string filename)
{
FileStream fs = new FileStream(filename, FileMode.Open);
// create a file stream
BinaryReader br = new BinaryReader(fs);
// create binary reader
DataRow row;
// create a new datarow
row = tbl.NewRow();
// set country field and image field
row[0] = name;
row[1] = br.ReadBytes((int)br.BaseStream.Length);
// add this row to the table
tbl.Rows.Add(row);
// clean up
br = null;
fs = null;
}
// Function: CreateData
// Creates a dataset that has 1 table with two fields: Country (string), and img (blob/byte[])
// Adds four records to this table
//
DataSet CreateData()
{
DataSet data = new DataSet();
// add a table 'Images' to the dataset
data.Tables.Add("Images");
// add two fields
data.Tables[0].Columns.Add("Country", System.Type.GetType("System.String"));
data.Tables[0].Columns.Add("img", System.Type.GetType("System.Byte[]"));
// add rows
AddImageRow(data.Tables[0], "argentina", Directory.GetCurrentDirectory() + "\\argentina.jpg");
AddImageRow(data.Tables[0], "canada", Directory.GetCurrentDirectory() + "\\canada.jpg");
return (data);
}
// Procedure: CreateReport
// Creates a report and passes the dataset
//
void CreateReport()
{
// create a report
CrystalReport1 cr = new CrystalReport1();
cr.SetDataSource(CreateData());
// pass a reportdocument to the viewer
crystalReportViewer1.ReportSource = cr;
}
public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();
//
// TODO: Add any constructor code after InitializeComponent call
//
CreateReport();
}
This is the coding part..ie,when the program is run the image which is existing in the directory (say argentina.jpg and canada.jpg). it will ask for country name...so if we type canada..then canada.jpg wil be displyed in the report.
This is wht the program does..
No I have to modify such that .. I have to add a buttn on the form say load..so when the load button is clicked, we should be able to load any image from the disk(any location) and that image should be displayed in the crystal report..How to do this..
please if any one change the coding part above and sent it .

Hi,
I am working with Drawing class.
My problem is I am unable to retain the previous drawing whenever i draw a new diagram.
Steps followed:
1. Draw a diagram(line) on Mouse up event.
2. When i draw the diagram second time using Mouse Up event, i am losing the previous diagram only new diagram is visible.
How to retain the previous and new diagram?
Thanks in advance.

Every time you redraw in your Paint event you need to redraw everything. There are at least two ways you could handle this (depending on what you need), one would be to keep a list of all lines that have been drawn and iterate through it on the Paint event redrawing them. The other would be to save the image as a bitmap and just redraw the bitmap every time you paint.

Thanks for the reply.
I got the answer waht I needed.

Typically, all your drawing code should be in the Paint event of your control or form. This is because part or all of your form/control can and will need to be redrawn at any time. Even if you don't have an event, like a button click or a mouse move to draw something in. Your application has to maintain a "database" of things that need to be drawn. Your app will modifiy this database using whatever methods you supply and the Paint code should interpret and draw everything in the database it needs to.

Hi,
Using C# code is it possible to know the OS type, whether it is 32 bit or 64 bit OS ????
Any help will be great.

Yes, the infact they have different runtime versions for 32 and 64bit.
Else try the good old autoconf check.
return Marshal.SizeOf(typeof(IntPtr));
Will return 4 for 32bit , and 8 for 64bit.

[C#]
public virtual int GetBytes(
string s,
int charIndex,
int charCount,
byte[] bytes,
int byteIndex
);
If the length of string s is less than the charCount, there will be a error.
How to solve it?
Thanks!

To find these, open a C++ project, type in the message, and hover the mouse over it.

You can't get a screenshot of anything that is not being drawn.
